Dihydrogen monoxide hoax

Dihydrogen monoxide (shortened to DHMO) is a scientific name for water that is relatively unknown to most of the public, used in hoaxes that illustrate how the lack of scientific knowledge and an exaggerated analysis can lead to misplaced fears. "Di" meaning two, and "Mono" meaning single, describes how water is made up of two hydrogen atoms and one oxygen atom (H2O).
